I really like the classy look of the Mercedes 300D. These cars are powered by an 87 hp 3 liter 5-cylinder engine and averages 30 miles per gallon.

Though it’s not much power for a car this size you have to remember this is a touring car and not a performance car. Mercedes built these cars like a tank and I could drive this car cross country without worry.

The only downside is that these cars don’t come cheap. Many cost upwards of 10K because owners know that fuel efficient cars are in high demand.
